what is the best way to make a pouch with a tie closure so that nothing comes out?
i was thinking i should cut the fabric in a circle, and then sew a pocket along the top to put the cord through, with an opening once or twice along the pocket to pull the cord tight. does anyone know what i'm talking about? i'm confusing MYSELF.... hehe

i want to make a cool dice bag for my boyfriend (loves the nerd games. hehe) for valentine's day. kind of a weird v-day gift, but i wanted to do it anyway, and then put papers with things i love about him, etc. inside. any extra suggestions on this part are very welcome as well. :)

thanks so much!
